Priority Storage

Post by PietroLHT » Fri Jun 02, 2017 4:15 pm

Considering how many people had requested a Priority Storage/ storage chest filter, I am suprised there isn't a blueprint for this already(not that I can find).

What it does?
It will request all the specified item in a logistic system and put them in a single location.
How does it work?
It reads the item count in the passive provider(s) and in the logistic system and request the difference between the two numbers.
Due to how the logistic system handle chests priority, the robot will move the items in active provider and storage chests before passive provider.
Because of this, you need to make sure there is no passive provider with the item in other location, or the robots may move the item from the passive provider to the requester and made a feedback loop

How do I use it?
After building the setup, change the Signal 0 to the item you want. Connect the powerpole to a roboport using a red wire. Watch your robots go to work.

There are 3 designs:
Single - items will be stored in a single provider chest. For things like a belt upgrading setup.

Array - items will be stored in an array of provider chests. This can be extended infinitely, however it is limited by thhe speed of inserters and can be a bit slow. For general storage use.

Array2 - another design for array, but use more requesters instead of using belt. Each requester will request evenly(not very reliable though). You will need to set the top arithmetic combinator with the count of requesters for it to work. You can also put the chest in different places given you keep them wired correctly. Good for modules upgrading setup.
